verify ldap email address and password

[jlory]

Does anyone know how I can verify an email address and password using a ldap directory? The ldap directory is a part of the email system I'm using, CommuniGate Pro. I can return a result for jamie.lory, but, I can't return anything for my password.

<?
if ($ds=ldap_connect("ldap.apigroupinc.com"))
{
print "Your connected to ldap.apigroupinc.com!";
print "<br>";
}
else
{
print "You failed to connect to ldap.apigroupinc.com";
}

                             if ($ds) { 
                             echo "Binding ..."; 			
                             $r=ldap_bind($ds);  			
                             echo "Bind result is ".$r."<p>";
	      }

          $dn = "cn=apigroupinc.com";
          $mail = "jamie.lory";
          $pass = "mypassword";

                    $filter="(|(mail=$mail)(password=$pass))";
                    $justthese = array("mail", "password");

                    $sr=ldap_search($ds, $dn, $filter, $justthese);

                    $info = ldap_get_entries($ds, $sr);

                    print $info["count"]." entries returned<p>";
